Anyone have any recommendations or thoughts on using a GPS with a PDA or PocketPC?

The www.MapTech.com site has some intriguing tidbits on this that tend to go over my head because I know next to nothing about PDA/PocketPCs.

Apparently, there are GPS units that can mate with these using wireless (Bluetooth?), USB or CompactFlash ports, then add the MapTech (or other?) software and the maps/charts and you'll never have an excuse to be lost again.

Incidentally, my main interest is for navigation on a small sailboat.
